Find The Sum of Common Alphabets - Lower Given two char arrays input1[] and input2[] containing only lower case alphabets, extract the alphabets which are present in both arrays (common alphabets). Get the ascii values of all the extracted alphabets. Calculate sum of those ascii values. Lets call it sum1 and calculate single digit sum of sum1, i.e keep adding the digits of sum1 until you arrive at a single digit. Return that single digit as output. Note: 1.Array size ranges from 1 to 10. 2.All the array elements are lower case alphabets. 3. Atleast one common alphabet will be found in the arrays. Example-1 input1: {'a', 'b', 'c'} input2: {'b', 'c'} output: 98 +99 = 197 1+9+ 7 = 17 1+7=8 Explanation: 'b' and 'c' are present in both the arrays. Ascii value of 'b' is 98 and 'c' is 99. Example-2 input1: {'g', 'q', 'r' } input2: {'r', 't', 'u'} output: 114 1+1+4= 6 Explanation: 'r' is present in both the arrays. Ascii value of 'r' is 114.
